About 2,100 people joined in a class action lawsuit for Chinese drywall homeowners filed in Louisiana, alleging that their homes were built with toxic wallboard manufactured by Knauf Plasterboard Tainjin Co. Ltd. (KPT).

The drywall lawsuit was filed Wednesday in the U.S. District Court for the Eastern District of Louisiana in New Orleans. The complaint was filed as part of an agreement where the Chinese company agreed to temporarily waive its rights to have lawsuits served through the Hague Convention for plaintiffs who joined the omnibus class action suit against the company by December 9.
